Exactly the same, or a bit different?

I have just noticed that the "num_uarts" option is not documented, but it
does exist:
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/drivers/mesa-hostmot2/hostmot2.c;h=223a224810c353529f6838c1189be8be118a2da5;hb=462f8094d2107178fe662add7b19ffab3a53c6cc#l433

As you are building from source it is possibly easiest to change uart.c
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/drivers/mesa-hostmot2/uart.c;h=40056f30bfde58e2752e7674ee66a9ede7d6efef;hb=462f8094d2107178fe662add7b19ffab3a53c6cc#l42

Change the 0, 4, 0x10, 0x000F part to appease the driver: ie 0, 4, 0x40,
0x000F

PCW would need to say which was correct as Master is also expecting UARTs
to have a 0x10 instance stride
